| Description |
A process (NTGG) for valorization of light naphtha and natural gas liquids is
described. The Process is based on modified zeolite materials. The modifications is two
kinds, one acidity modification and the other is modification by metals. In the former as
well as latter cases the acidity and acid strength distributions are evaluated. Attempts have
been made to correlate with acidity. The nature of enhanced acid sites and role of extra
frame work aluminum in the mildly hydrothermally treated ZSM-5 catalysts, is elucidated.
Among the metal modified catalysts Zn-Al-silicate showed lower deactivation rates. Based
on various reaction pathways such as creaking, hydrogen transfer, oligomerization and
dehydrogenation, a rational explanation for the role of Zn is provided. The NTGG processes
for optimization of LPG as well as aromatics is discussed in detail.
